how far and how near...

If it is a diagram, then I would know how far and how near point A to point B.  The relationships of everything can easily be discussed in the context of whole and part. But life is far from being a diagram that can be easily drawn on paper. Whole and part can be very elusive and it is not that easy to relate and comprehend. Visiting a sick person is thus a good exercise for mind to visualize one's journey from point A to point B. It can just put us, and anybody for that matter into a powerless position no matter who we are. Allahuakbar.
